According to the United States Geological Survey (USGS), today a 6.7 magnitude tremor 26 kilometers from the town that inhabits Burias, located at the southern end of Philippines, with a hepicenter 77 kilometers deep. However, the danger has not passed since because this earthquake It was in an area of islands, it is feared that there could be a tsunamialthough so far there is no official alert from the authorities.
It was through several videos shared in social networks where you can see the great damage and destruction caused by this event, an example of this is a video in a shopping center where you can see people running or taking cover under tables, while things fall and move.
Likewise, in another shared video you can see how the sea receded for a few moments after the earthquaketherefore the suspicion of tsunami.
The USGS explained that the sea of Philippines It is located in an area known as the Pacific Ring of Fire, this is an area known for having a large amount of seismic and volcanic activity, where approximately 7 thousand earthquakes are recorded annually, this because it borders the long plates of the Pacific and Eurasia. and the small Sunda plate. In fact, the Pacific plate subducts beneath the mantle, very close to Japan, a country where earthquakes also frequently occur.
Why are you shaking a lot lately?
Surely you have noticed that lately there are lots of news about earthquakes of great magnitude occurred around the world and you may have wondered why, however, not even the most experts seismologists can give an answer to this question.
“The earthquakes They are a phenomenon inherent to the interior of the Earth, and have nothing to do with atmospheric or any other phenomena,” explained Luis Robles, researcher at the Department of Seismology of the Institute of Geophysics of the National Autonomous University of Mexico.
In fact, each year there are around 200,000 earthquakes on the planet, but many of these go unnoticed because they are very mild or because they occur in areas far from populations. These occur as a measure of sudden release of tension in the Earth’s crust.
“We know that tension is accumulating in the large faults and we know where they are, but we have no way of knowing when they will release it.” […] In physical terms it is completely unpredictable.”commented Richard Luckett, seismologist from the British Geological Survey.
